Build your GoodWe ESA
Start where you need to. Stack the rest later.
GoodWe ESA is built in layers — one inverter, with modules added on top as your needs grow. Size it below and watch it build.
1 Your power supply
Your switchboard tells us for certain — we confirm it on site.
2 Inverter
How much power the system can deliver to the house at once.
What does kW output mean?
Output is how much electricity the system can deliver at any one moment, measured in kilowatts. A kettle draws about 2 kW; ducted air conditioning 4 to 6 kW. A higher output runs more things at once. It does not change how long your stored power lasts — that is the battery’s job.
3 Charging a car
Optional. Skip it if there is no EV, or no EV yet.
4 How much storage
Drag it. We work out the modules that make that capacity.
What is a kilowatt-hour?
A kilowatt-hour is a unit of energy — one kilowatt drawn for one hour. It is the unit your electricity bill charges you for. Storage is measured the same way, so 9 kWh holds enough to run a 1 kW load for nine hours, or a 3 kW load for three.

BACKED BY US, NOT JUST THE MANUFACTURER
A 10-year workmanship warranty on solar and battery installations.
Manufacturers cover their products. We cover the installation. For 10 years from practical completion, a defect that comes from our workmanship in installing your solar panels, inverter or battery — the mounting, the cabling, the installation work — is put right by us: repaired, re-done, or the affected installation part replaced, at our cost and at our choice of remedy.
- It stays with the home. Sell up, and the new owner gets the remainder, on the same terms.
- Switchboard, EV charger and heat pump installation work carries its own 1-year workmanship warranty from the date of installation.
- It covers our work, not the products. A panel, inverter or battery fault is a manufacturer warranty matter, with its own period.
- What it does not cover: damage from misuse, changes or repairs by someone else, storms, surges and grid events, pests and corrosion, building movement, ordinary wear, and internet or monitoring problems. A call-out where no workmanship fault is found may be charged.
- Keep your rights. It adds to the Australian Consumer Law guarantees, never replaces them.
- To claim: email engineering@solar4life.com.au or call 1300 997 005 with your name, the installation address, what is wrong and photos. Tell us promptly; delay can affect a claim.
Residential installations. The full terms are in your installation agreement.
